Questão jurídica principal
Whether architect G. had to be disqualified for bias after settlement efforts during the expert inspection.
Decisão extraída
A bias challenge does not require subjective bias or proof of actual bias; objective circumstances may suffice. Here, however, the expert's settlement efforts and assessment of the case did not objectively justify a disqualification.
Fundamentação extraída
An expert may be challenged if objective circumstances create an appearance of partiality. But merely making a comparative assessment after inspecting the facts, and even proposing a settlement, does not by itself establish a relevant appearance of bias; otherwise parties could too easily evade unfavorable expert opinions.
